Today,  August 8, 2006, the Registrant is issuing a press release  (Exhibit 99.1

ITEM 5.02        DEPARTURE OF DIRECTORS OR PRINCIPAL OFFICERS;
                 ELECTION OF DIRECTORS; APPOINTMENT OF PRINCIPAL OFFICERS

Charles J.  Kretschmer,  a director  and  President  and COO of the  Registrant,
resigned as a director effective August 3, 2006. On that date, he also submitted
his  resignation as President and COO, to become  effective  September 30, 2006.
See Item 1.02 above. After September 30, 2006, Mr. Kretschmer will become a Vice
President  (a   non-"executive   officer"   position)  of  the  Registrant  with
responsibility  primarily  for  acquisition  /  divestiture  activity,  contract
manufacturing   for  the   Communications   segment,   selected  major  contract
negotiations  and  profit  improvement  initiatives.  Mr.  Kretschmer  has  been
President and COO of the Registrant since October 2002.

Victor L. Richey, Jr., currently Chairman and Chief Executive Officer ("CEO") of
the Registrant,  will also become  President  effective  September 30, 2006. Mr.
Richey has been CEO of the Registrant  since October 2002.  Since April 2003, he
has  also  been  Chairman.   Further   information   concerning  Mr.  Richey  is
incorporated  herein by reference to (i) the Registrant's  Proxy Statement dated
December 21, 2005 under the headings  "NOMINEES AND  CONTINUING  DIRECTORS"  and
"EMPLOYMENT  AGREEMENTS",  and (ii)  Registrant's  Form 10-K for the fiscal year
ended  September  30,  2005  under  the  heading  "EXECUTIVE   OFFICERS  OF  THE
REGISTRANT."


ITEM 7.01        REGULATION FD DISCLOSURE

Today,  the  Registrant  is issuing a press release  announcing  its fiscal 2006
third  quarter  financial  and  operating  results,  and will  conduct a related
Webcast  conference  call at 4:00 p.m.  central  time.  This  press  release  is
furnished  herewith  as  Exhibit  99.1,  and will be posted on the  Registrant's
website located at http://www.escotechnologies.com. It can be viewed through the
"Investor  Relations"  page  of the  website  under  the tab  "Press  Releases,"
although the Registrant  reserves the right to discontinue that  availability at
any time.


NON-GAAP FINANCIAL MEASURES

The press release furnished herewith as Exhibit 99.1 contains financial measures
and  financial  terms not  calculated  in  accordance  with  generally  accepted
accounting  principles  in the  United  States of America  ("GAAP")  in order to
provide  investors and management  with an alternative  method for assessing the
Registrant's operating results in a manner that is focused on the performance of
the Registrant's  ongoing  operations.  The Registrant has provided  definitions
below  for the  non-GAAP  financial  measures  utilized  in the  press  release,
together with an  explanation  of why management  uses these  measures,  and why
management  believes  that  these  non-GAAP  financial  measures  are  useful to
investors.  The press release uses the non-GAAP financial measures of "EBIT" and
"EBIT margin".

The  Registrant  defines  "EBIT" as  earnings  before  interest  and taxes.  The
Registrant  defines  "EBIT  margin"  as  EBIT as a  percent  of net  sales.  The
Registrant's  management  evaluates the  performance  of its operating  segments
based on EBIT and EBIT margin, and believes that EBIT and EBIT margin are useful
to investors to demonstrate the operational  profitability  of the  Registrant's
business segments by excluding interest and taxes, which are generally accounted
for across the entire  Registrant on a consolidated  basis.  EBIT is also one of
the measures used by management in determining  resource  allocations within the
Registrant and incentive compensation.

The  presentation of the  information  described above is intended to supplement
investors'   understanding  of  the  Registrant's  operating  performance.   The
Registrant's   non-GAP  financial  measures  may  not  be  comparable  to  other
companies' non-GAAP financial performance measures.  Furthermore, these measures
are not  intended  to replace net  earnings,  cash  flows,  financial  position,
comprehensive  income  (loss),  or any other measure as determined in accordance
with GAAP.
